DEVICE FOR USE IN THE MANUFACTURE OF RAIL-JOINTS.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filerl July 19,1904. Serial No. 217,284.

To all whom it may concern.-

Be it known that I, HENRY B. NICHOLS, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Devices for Use in the Manufacture of Rail -Joints, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention has relation to apparatus for use in the manufacture of railway-rail joints of the type described and claimed in Patents Nos. 673,829 and 717,025 and Reissue No. 12,074, in which the bases or feet of the rails are surrounded by a body of filling material, such as spelter or other suitable metal, applied in a molten condition.

The object of my invention is to provide means of simple character which can be readily and conveniently applied to the joint and removed therefrom for the purpose of form ing a dam to prevent the molten metal from escaping through the opening between the meeting edges of the base portions of the joint-plates.

To this end my invention consists in a removable dam for closing the said opening and means for securing said dam in place, all substantially as hereinafter described, and pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a plan view of a rail-joint with the device embodying myinvention applied thereto; Fig. 2, a plan View of the device reilpoved, and Fig. 3 a section on the line 3 3 of 1 1 designate the jointed rails; 2 2, the joint-plates of the character described in the above-mentioned patents and which form the space 3 about the bases of the rails which is to be filled with molten metal.

4 designates the dam for closing the longitudinal opening 5 between the base portions This dam consists of a flat strip or bar covered with'asbestos cloth 6 or other material of a refractory nature and carried by the supports 7, to which it is se -tions 2 of the jointplates in the manner shown. As the buttons are forced over the inclined surfaces 2" the dam 4 is drawn up closely against the under surfaces of the plates to effectually close the opening 5. The openings at the ends of the joint-plates are luted with clay or otherwise closed, and the molten metal is poured into the space 13 through the openings 10. The device is then removed and applied to another joint.

I do not limit myself to the precise details of construction which I have herein shown and described,as these may be changed without departing from my invention.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. The herein-described device for use in the formation of railway-rail joints, consisting of a dam arranged to seat over and close the longitudinal bottom opening between the base portions of joint-plates, and means for supporting said dam.

2. The herein-described device for use in the formation of railway-rail joints, consisting of an elongated bottom dam, carriers therefor, and securing devices on said carriers, and arranged to engage the joint to thereby hold the device in position.

3. The herein-described device for "use in the formation of rail-joints, consisting of an elongated damming-strip having a refractory covering, carriers to which said strip is secured, and supporting devices pivoted to said carriers.

In testimony whereof I have affixed my signature in presence of two witnesses.
